Identifying Grass Seedlings

Crabgrass, smooth (Digitaria ischaemum)

Summer annual grasses

Description

Smooth crabgrass has weak stems that result in a decumbent growth habit. It often roots at its lower nodes, which gives it a sprawling appearance. Its stems and both leaf surfaces are hairless or have a few sparse hairs. The blades are flat and 5–10 mm wide. Auricles are absent, and the ligule is a jagged membrane 0.5–2 mm long.
